Recombinant Human IL34, N-His

Introduction

Recombinant Human IL34, also known as Interleukin 34, is a cytokine that plays a crucial role in the regulation of the immune system. It is a protein that is produced through genetic engineering techniques, making it a recombinant protein. This article will provide a scientific description of the structure, activity, and applications of Recombinant Human IL34.

Structure of Recombinant Human IL34

Recombinant Human IL34 is a 39 kDa protein that is composed of 242 amino acids. It is a homodimer, meaning it is made up of two identical subunits. Each subunit contains a conserved immunoglobulin-like domain and a fibronectin type III-like domain. These domains are important for the binding and activation of its receptor, Colony Stimulating Factor 1 Receptor (CSF1R).

The crystal structure of Recombinant Human IL34 has been determined, revealing a unique three-dimensional structure. The immunoglobulin-like domain forms a β-sandwich structure, while the fibronectin type III-like domain adopts a β-barrel fold. These structural features allow Recombinant Human IL34 to interact with CSF1R and initiate downstream signaling pathways.

Activity of Recombinant Human IL34

Recombinant Human IL34 acts as a cytokine, which is a type of signaling molecule that regulates the immune system. It is primarily produced by cells in the bone marrow, skin, and brain. Its main function is to bind to and activate CSF1R, which is expressed on the surface of immune cells such as macrophages and monocytes.

Upon binding to CSF1R, Recombinant Human IL34 triggers a cascade of events that result in the activation and proliferation of these immune cells. It also promotes the differentiation of monocytes into macrophages, which are essential for the immune response against infections and diseases.

In addition to its role in the immune system, Recombinant Human IL34 has also been shown to have neuroprotective effects. It can promote the survival and growth of neurons, making it a potential therapeutic target for neurodegenerative diseases.

Applications of Recombinant Human IL34

Due to its role in regulating the immune system, Recombinant Human IL34 has several potential applications in the field of medicine. One of its main applications is in the treatment of autoimmune diseases, where the immune system attacks the body’s own tissues. By targeting CSF1R, Recombinant Human IL34 can modulate the activity of immune cells and reduce inflammation in autoimmune diseases such as rheumatoid arthritis and multiple sclerosis.

Recombinant Human IL34 also has potential in cancer therapy. CSF1R is overexpressed in many types of cancer, and its activation can promote tumor growth and metastasis. By blocking the interaction between Recombinant Human IL34 and CSF1R, it may be possible to inhibit the growth and spread of cancer cells.

Furthermore, Recombinant Human IL34 has been investigated as a potential treatment for neurodegenerative diseases, such as Alzheimer’s and Parkinson’s disease. Its neuroprotective effects make it a promising candidate for the development of new therapies for these conditions.

Conclusion

In summary, Recombinant Human IL34 is a cytokine that plays a crucial role in the regulation of the immune system. Its unique structure allows it to bind and activate its receptor, CSF1R, leading to the activation and proliferation of immune cells. This protein has potential applications in the treatment of autoimmune diseases, cancer, and neurodegenerative diseases. Further research on Recombinant Human IL34 may uncover more therapeutic benefits and pave the way for the development of new treatments for various diseases.
